This is general information for US drivers and riders, written in our own words. Laws differ by state and change over time, so check the official links and your state's rules. It is not legal advice.

Get the price in writing before work starts

  • Many states require a written estimate before a shop starts work, and some require your signature before the price goes up.
  • Ask for parts and labor listed separately. Do not sign a blank authorization.
  • If the shop finds more work, ask them to call you with the new price before they do it, and keep that in writing.

Ask to see (or keep) the old parts

  • Asking for your old parts back is a normal request. Say so when you approve the work, not after.
  • Some states require shops to return replaced parts if you ask. Some parts, like those returned under warranty, may be kept by the shop.
  • Seeing the worn part is an easy way to check that a repair was needed.

Independent service does not automatically void your warranty

  • A federal law (Magnuson-Moss) generally stops a maker from voiding your warranty only because someone other than the dealer did routine service or because you used non-brand parts.
  • The maker can deny a claim if they show that the part or the work caused the problem.
  • Keep dated receipts for every service. Our service log helps, and receipts are what you point to if a claim is questioned.

Safety recall repairs are free

  • If a safety recall applies to your exact vehicle, the maker's dealer fixes it at no cost to you.
  • Recalls may apply to many cars. Only a check with your VIN gives the exact answer.
  • If a shop says you must pay for a recall repair, ask them to check the recall number and call the maker.

Lemon laws: the basics

  • Every state has a lemon law for new vehicles with a serious problem the maker cannot fix after a reasonable number of tries. Details, time limits and which vehicles count vary by state.
  • Keep every repair order, with dates and the problem described, and write to the maker if the problem comes back.
  • Used cars are covered less often. Check your state's rules before you buy.

Where to complain

  • Start with the shop's manager, in writing, and say what you want fixed.
  • Then your state attorney general or consumer protection office. Many also have a dedicated auto repair agency.
  • Report safety defects to NHTSA, and scams or unfair practices to the FTC.
